The IRS Just Raised Its Mileage Rate Mid-Year — Here's What It's Worth

If you drive for your business — sales calls, client visits, deliveries, job sites — the deduction you've been calculating all year just got more complicated, and more valuable. The IRS raised its standard business mileage rate to 76 cents per mile for any driving done from July 1 through December 31, 2026, up from 72.5 cents for the first half of the year. It's the first time the IRS has adjusted the rate mid-year since 2022, and it means 2026 is a split-rate year: two different numbers, two different halves, and a recordkeeping requirement most small business owners haven't dealt with before.

Why the IRS Moved Mid-Year

The IRS sets its standard mileage rate annually based on an analysis of the fixed and variable costs of operating a vehicle — fuel, maintenance, insurance, depreciation. Rate changes almost always happen once a year, announced in December for the following January. A mid-year adjustment is unusual specifically because it signals the IRS saw enough movement in fuel prices during the first half of 2026 to justify breaking from that pattern. The agency made the same kind of mid-year move in 2022, when gas prices spiked sharply — this is only the second time it's happened in recent memory.

Alongside the business rate, the IRS also raised the mileage rate for medical and moving purposes, from 20.5 cents to 23.5 cents per mile, effective the same July 1 date. The charitable mileage rate, which is fixed by statute rather than set by the IRS, did not change and remains at 14 cents per mile.

What This Means in Real Dollars

The rate applies per mile driven for business purposes — client meetings, supply runs, job-site travel, and other business use of a personal vehicle. It doesn't matter whether the vehicle is gas, diesel, hybrid, or electric; the same rate applies across the board. For a business owner or self-employed contractor who logs meaningful mileage, the increase adds up quickly:

• A consultant driving 1,000 business miles a month from July through December logs 6,000 miles at the new rate. That's $4,560 in deductible mileage for the second half of the year alone, versus $4,350 at the old rate — an extra $210 in deductions from the rate change alone.
• A contractor or field-service business running multiple vehicles will see that gap multiply across every vehicle and every driver on payroll using a personal car for work.
• Rideshare, delivery, and other high-mileage self-employed workers will feel the increase the most, since deduction size scales directly with miles driven.

The Recordkeeping Catch

Here's where it gets tricky: you can't just apply 76 cents to every business mile driven in 2026. The IRS requires the 72.5-cent rate for any mileage logged between January 1 and June 30, and the 76-cent rate only for mileage from July 1 onward. That means your mileage log — assuming you're keeping one — needs a clear dividing line at the midyear mark.

If you've been tracking mileage in a single running total for the year, now is the time to split it. Pull your log, separate trips before and after July 1, and apply the correct rate to each half. Mileage-tracking apps that log dates automatically make this simple; a shoebox of gas receipts does not. Either way, the IRS still requires contemporaneous records — the date, business purpose, and mileage of each trip — not an estimate reconstructed at tax time.

Standard Mileage Rate vs. Actual Expenses

The standard mileage rate is a simplified alternative to deducting actual vehicle expenses — gas, repairs, insurance, depreciation — line by line. Business owners can choose whichever method produces the bigger deduction, but only under certain conditions. If you want to use the standard mileage rate, you generally need to choose it in the first year the vehicle is used for business; switching from actual expenses to standard mileage later is restricted. If your business already uses actual expense tracking, this mid-year mileage bump doesn't directly apply to you, but it's a good prompt to run the comparison and confirm you're still using the more favorable method.

This is also a useful moment to revisit how vehicle costs flow into your broader books. If mileage deductions and vehicle expenses aren't clearly reflected in your profit and loss statement, the mid-year rate change is a good trigger to clean that up before the numbers get harder to untangle at year-end.

Who Should Pay Closest Attention

This rate change matters most for a specific set of small business owners:

• Self-employed contractors and consultants who drive to clients or job sites and claim mileage on Schedule C.
• Real estate agents logging heavy mileage for showings and client meetings.
• Home-service businesses — plumbers, electricians, landscapers, cleaners — with employees or owners driving personal vehicles between jobs.
• Sales teams reimbursed at the IRS standard rate rather than a flat car allowance.
• Businesses that reimburse employees for mileage, since reimbursements at or below the IRS rate remain non-taxable to the employee — a reimbursement policy that hasn't been updated for the July 1 change may be underpaying staff or overpaying based on outdated math.

If your business reimburses employees for driving, this is also worth a quick policy check. Reimbursement plans tied to the old 72.5-cent rate should be updated for trips taken on or after July 1 to stay accurate and to keep those reimbursements properly non-taxable.

The Bottom Line

A three-and-a-half-cent bump per mile sounds small until it's multiplied across every business mile driven for six months. For businesses that log serious mileage, this is real money — but only if the recordkeeping is split correctly at the July 1 line. The fix is simple: update your mileage log or app now, confirm it's tracking the date of each trip, and apply 72.5 cents to the first half of the year and 76 cents to the second. Businesses just getting their financial tracking in order might also use this as a prompt to revisit fundamentals like a dedicated business bank account, which makes separating and substantiating vehicle expenses far easier come tax time.
